Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531562, here are decompositions:

11 + 531551 = 531562
41 + 531521 = 531562
179 + 531383 = 531562
263 + 531299 = 531562
281 + 531281 = 531562
359 + 531203 = 531562
389 + 531173 = 531562
419 + 531143 = 531562

Showing the first eight; more decompositions exist.
